This patch implements a new QMP request named "cpu-model". It returns the cpu model of cpu 0. eg:
request: '{"execute" : "query-cpu-model" } answer: '{"return" : "2817-ga1" } Alias names are resolved to their respactive machine type and GA names already during cpu instantiation. Thus, also a cpu name like "host", which is iplemented as alias, will return its normalized cpu model name.
